IMPROVEMENT IN CLOTH-SHEARING MACHINES.

Specification forming part of Letters Patent No. 148,171, dated March 3,1874; application filed D cember 23, 1873.

To all whom it may concern:

Be it known that I, ADNA BROWN, of Springfield, in the county of Windsorand State of Vermont, have invented a new and useful Improvement inCloth-Shearing Machines 5 and that the following is a full, clear, andexact description of the same, reference being had to theaocompanyingdrawings, and to the letters of reference marked thereon, making a partof this specification.

This invention is in the nature of an improvement in a machine forshearing woolen cloths; and the invention consists in a changeablebrush-rest alone, and in combination with a nap-raising brush, aflock-removing brush, and a flock-catcher, ashereinafter described andclaimed.

In shearing machinery heretofore constructed great difficulty has beenexperienced in shearing different kinds of cloths on the same machinesome cloths working to a better advantage against what is known as thedead or flat side, others working better against a roller, so that ithas been found necessary to change the brush-rests from time to time,sometimes using a dead or flat surface, and at others a roller.

In the accompanying sheet of drawings, Figure l is a cross-section takenin the line w 00, Fig. 2; and Fig. 2 is a plan or top view of myinvention.

Similar letters of reference indicate like parts in the several figures.

A represents the supporting-frame for the shears, shear-rest, brushes,and other appliances common. to a shearing-machine. B is the shear-restor surface over which passes the cloth 0 while being sheared. D is thebrush which raises the nap on the cloth. These several parts, in theirconstruction and operation, being old and well known in shearing-machines, need no further description. Secured to the frame A, immediatelyabove the napraising brush D, is brush-rest, E. This brush-rest isprovided at 1 end with suitable journals, fitting into correspondinghearings in the frame A, and is provided on one side with a roller, f,and a fin, g, on the other. Fitted to the frame A, above thelast-described rest E, and between the said rest and the shearingrest B,is a brush, F. Affixed to the base of the frame A, in any suitablemanner, is a shell, G. This shell may be constructed of metal or anysuitable material, and is of an irregular form, as shown in the sectionthereof, Fig. 1.

My invention being constructed substantially as I have described, itsoperation is as follows: When brushing up the nap on that class of goodswhich requires a dead or fiat surface to support it against the actionof the brush, it is simply necessary to revolve the rest E until theedge of the fin 9 thereof brings the cloth against the brush, when adead or flat surface rest is obtained; and when it is desired to brushup the nap on that class of goods requiring a curved or cylindricalsurface, the rest E is revolved until the roller f forces the cloth tothe action of the nap-raising brush D, so that, without loss of. time orchange of machinery, the rest best adapted to the kind of cloth to benapped and sheared is had.

The rest E may be revolved by a hand-wheel, H, or by any suitablemechanism, and it is held in any desired position by the ratchet h andpawl 17.

As the cloth 0 passes over the shear-rest B, its under surface'isbrought in contact with the revolving brush F, which not only brushesthe cloth free from the flock which has accumulated thereon, (and inthis way prevents it from being carried onto the shear-rest B,where, asbefore stated, it would produce damaging results,) but it throws theflock thus brushed off into the shell G, wherein it is gathered, andprevented from flying and again being deposited on. the goods, thisshell being formed, as will be seen, with a double curve, the upper oneof which catches the flock as it is brushed from the cloth, and theunder one acting as a receptacle to hold and confine the flock.

From the foregoing, it will be seen that, by reason of my improvementsin a shearing-machine, I have produced a brush-rest combining in thesame rest the forms of rest best suited to the different kinds of cloth,and easily and quickly adjusted without change of parts; and I have alsoproduced a device for removing the flock from the under side of thecloth, and a device for catching the flock as it is removed, andpreventing it from being again deposited on the cloth. thus preventingthe damage that frequently occurs from the accumulation of the tlockbetween the shearing rest and cloth, as before recited.

hat I do claim as new. and desire to se cure by Letters Patent, is-

1. A shearing-nmehine constructed with a revolving brush-rest. said resthaving two or more diii'erent surfaces. any one of which may be used, asdesired. substantially as and for the purpose described.

2. In a shearing-machine. the combination of the nap-raising brush.changeable bruslr rest, and flock-removing brush. constructedbrush-rest, constructed and operated as (10- V scribed, in combinationwith the nap-raising brush. as specified.
